The community history society my husband and I belong to went to see this exhibit ( scroll) at the University of Colorado at Boulder on Friday. It has an as mazing story! .
Info from the university's website: "A breathtaking stone tool cache unearthed in the Boulder city limits that contains elaborate stone knives and blades used to butcher ice-age mammals 13,000 years ago is... on exhibit at the University of Colorado Museum of Natural History
Discovered by a landscaping crew digging a fishpond in the yard of a Boulder home in 2008, the 83-piece tool cache was packed in a space about the size of a shoebox under two feet of soil, apparently untouched for millennia. The tools were discovered in the yard of Boulder homeowner Patrick Mahaffy, who is loaning them to the CU Museum as the centerpiece of the new exhibit, “Unearthed: Ancient Life in the Boulder Valley.”
CU-Boulder Professor Douglas Bamforth, who has been studying the tools for several years, said they were left behind for reasons unknown by nomadic hunter-gatherers. Protein residue tests on the tools, collectively known as the Mahaffy cache, showed two of the bifacial knives were used to cut up American camels and horses, which went extinct at the end of the last ice age. Residue of ancient bear and sheep protein was found on two other Mahaffy cache tools, he said."
